  • The Histopathology of Antique Ark's Mantle (Anadara Antiquata) Post
    The histopathology of antique ark’s mantle (Anadara antiquata) post-depuration with the shells’ filtration Nabila A. Putri, Laksmi Sulmartiwi, Kustiawan T. Pursetyo Faculty of Fisheries and Marine, Universitas Airlangga, 60115, Surabaya, Indonesia. Corresponding author: L. Sulmartiwi, [email protected] Abstract. Cockles are marine organisms which have the character of filter feeders so that heavy metals can be neutralized naturally through their shells. However, not all heavy metals can be neutralized, so depuration needs to be done. After depuration, histopathological analysis is needed to determine the condition of the soft tissue of the shells so that the disease can be diagnosed through structural changes that occur in the organs that are the main target of pollutants. This study aims to determine the histopathology of antique ark’s mantle (Anadara antiquata) after post-depuration with the filtration of the cockles’ shells. This research method applies an experimental method with scoring histological damage to antique ark’s mantle that ranges from 0 to 3, depending on the level and extent of the changes that occur. After that, the distribution of normal and non-homogeneous data was obtained, and then the Kruskal-Wallis non-parametric test was conducted. The main parameter is the histopathology of the antique ark’s mantle. Supporting parameters include water quality, namely temperature, dissolved oxygen (DO), nitrate, nitrite, ammonia, salinity, levels of heavy metals Pb and Cd, total suspended solid (TSS) and total dissolved solid (TDS). The results of the Kruskal-Wallis statistical analysis shows no significant difference between treatments P0 (Control), P1 (Filter 25%), P2 (Filter 50%), P3 (Filter 75%), and P4 (Filter 100%).

E-mails: [email protected], [email protected] 2Corresponding author Abstract Diadema setosum (Leske, 1778), a widespread tropical echinoid and key herbivore in shallow water environments is cur- rently expanding in the Mediterranean Sea. It was introduced by unknown means and first observed in southern Turkey in 2006. From there it spread eastwards to Lebanon (2009) and westwards to the Aegean Sea (2014). Since late 2016 spo- radic sightings of black, long-spined sea urchins were reported by recreational divers from rock reefs off the Israeli coast. Numerous attempts to verify these records failed; neither did the BioBlitz Israel task force encounter any D. setosum in their campaigns. Finally, a single adult specimen was observed on June 17, 2017 in a deep rock crevice at 3.5 m depth at Gordon Beach, Tel Aviv. Although the specimen could not be recovered, spine fragments sampled were enough to genet- ically verify the visual underwater identification based on morphology. Sequences of COI, ATP8-Lysine, and the mito- chondrial Control Region of the Israel specimen are identical to those of the specimen collected in 2006 in Turkey, unambiguously assigning the specimen to D.

E-mail: [email protected] 2 Conservation International Indonesia Marine Program. Jl. Dr. Muwardi No. 17, Renon, Denpasar 80235 Indonesia. Abstract A checklist of shallow (to 60 m depth) reef fishes is provided for the Bird’s Head Peninsula region of West Papua, Indonesia. The area, which occupies the extreme western end of New Guinea, contains the world’s most diverse assemblage of coral reef fishes. The current checklist, which includes both historical records and recent survey results, includes 1,511 species in 451 genera and 111 families. Respective species totals for the three main coral reef areas – Raja Ampat Islands, Fakfak-Kaimana coast, and Cenderawasih Bay – are 1320, 995, and 877. In addition to its extraordinary species diversity, the region exhibits a remarkable level of endemism considering its relatively small area. A total of 26 species in 14 families are currently considered to be confined to the region.

  • Invertebrate Predators and Grazers
    9 Invertebrate Predators and Grazers ROBERT C. CARPENTER Department of Biology California State University Northridge, California 91330 Coral reefs are among the most productive and diverse biological communities on earth. Some of the diversity of coral reefs is associated with the invertebrate organisms that are the primary builders of reefs, the scleractinian corals. While sessile invertebrates, such as stony corals, soft corals, gorgonians, anemones, and sponges, and algae are the dominant occupiers of primary space in coral reef communities, their relative abundances are often determined by the activities of mobile, invertebrate and vertebrate predators and grazers. Hixon (Chapter X) has reviewed the direct effects of fishes on coral reef community structure and function and Glynn (1990) has provided an excellent review of the feeding ecology of many coral reef consumers. My intent here is to review the different types of mobile invertebrate predators and grazers on coral reefs, concentrating on those that have disproportionate effects on coral reef communities and are intimately involved with the life and death of coral reefs. The sheer number and diversity of mobile invertebrates associated with coral reefs is daunting with species from several major phyla including the Annelida, Arthropoda, Mollusca, and Echinodermata. Numerous species of minor phyla are also represented in reef communities, but their abundance and importance have not been well-studied. As a result, our understanding of the effects of predation and grazing by invertebrates in coral reef environments is based on studies of a few representatives from the major groups of mobile invertebrates. Predators may be generalists or specialists in choosing their prey and this may determine the effects of their feeding on community-level patterns of prey abundance (Paine, 1966).

Among these, A. aureus and A. ternatensis have not been reported from Japanese waters. A key, brief descriptions and illustra tions are provided for these four species. Damselfishes of the genus Amblyglyphidodon are commonly found at coral reefs in the tropical Indo-West Pacific region and easily distinguished from other damselfishes in having an orbicular body. This genus is composed of only six species, of which four are distributed in the tropical western Pacific (Allen, 1975). In Japan, there have been known only two species, A. curacao and A. leucogaster, from the Ryukyu Islands (Aoyagi, 1941; Matsubara, 1955; Masuda et al, 1980). During the course of studies on damselfishes from the Ryukyu Islands, we have collected two other species, A. aureus and A. ternatensis. A careful examination of these four species has revealed that some key characters used by Allen (1975) to distinguish A. ternatensis from the other three species are not valid for our specimens. In this report we describe and illustrate these four species from the Ryukyu Islands with some discussions on the taxonomic characters.

Address correspondence to W. L. Smith at the address above, or e-mail: [email protected]. Abstract Knowledge of evolutionary relationships or phylogeny allows for effective predictions about the unstudied characteristics of species. These include the presence and biological activity of an organism’s venoms. To date, most venom bioprospecting has focused on snakes, resulting in six stroke and cancer treatment drugs that are nearing U.S. Food and Drug Administration review. Fishes, however, with thousands of venoms, represent an untapped resource of natural products. The first step in- volved in the efficient bioprospecting of these compounds is a phylogeny of venomous fishes. Here, we show the results of such an analysis and provide the first explicit suborder-level phylogeny for spiny-rayed fishes. The results, based on ;1.1 million aligned base pairs, suggest that, in contrast to previous estimates of 200 venomous fishes, .1,200 fishes in 12 clades should be presumed venomous.
